Center High School in California Upgrades Stadium with One Systems
Nashville, Tennessee, November, 2009 – When Center High School decided to upgrade
the sound system in Gerety Stadium, home to football and soccer games, as well as other
events like the school’s commencement ceremonies, they chose speakers from One Systems.
Center High School, located in Sacramento, California had been hanging on to their outdated,
voice only sound reinforcement system for years, and tapped Advance Sound and Electronics
of Sacramento for a new installation. Gerety stadium, which seats 3,000, is an example of a
high-noise sports environment requiring highly intelligible speakers that can withstand the
elements and perform well for both music and spoken applications.
Advance Sound and Electronics chose One Systems speakers because of their ability to
produce high quality sound for both voice and music, as well as their compact size, direct
weather design, and desirable mounting options. “These speakers sound great, they are more
powerful than we ever expected and the mounting accessories really helped the installation
along, “ says Bob Becker, Senior AV Consultant of Advance Sound and Electronics.
The installation includes both 112IM and 108IM speakers, each pole mounted throughout the
stadium, with four specially mounted to cell phone towers. The 112IM speakers were chosen to
adorn the facility because of their excellent pattern control, the high output, its weatherproof
design and their intelligibility. The 112IMs utilize a single 12” I/O woofer and a large format ET
driver coupled to a fully rotatable high frequency horn. Two 112IM speakers on the home team side, along with two 108IM’s on the visitor team side were installed to produce sound strictly for
the playing field. The remaining speakers are strategically placed around the stadium. The
112IM and 108IM speakers both offer Equivalent Throat design, which extend bandwidth polar
control and offer very low distortion for a variety of high frequency radiation patterns.
The challenge of this installation was being able to have high musicality and speech intelligibility
for the bleachers as well as the players, without noise spilling over into nearby neighborhoods.
“With the previous sound system, neighbors a half-mile from the stadium could hear the game
and we could not have that happen with this installation. With the new system, the spillover into
the residential areas is minimal. One Systems met and exceeded all of our needs and
expectations; we are very pleased with the results. More important, the school is pleased,” says
Becker.
